A Novel Measurement Using Digital Radiography to Minimize Fluoroscopy in Total Hip Arthroplasty

AbstractPreoperative templating for total hip arthroplasty (THA) is fraught with uncertainty. Specifically, the conventional measurement of the lesser trochanter to the center (LTC) of the femoral head used in preoperative planning is easily measured on a template but not measurable intraoperatively. The purpose of this study was to examine the utility of a novel measurement that is reproducible both on templating and in surgery as a more accurate and practical guide. We retrospectively reviewed 201 patients with a history of osteoarthritis who underwent primary THA. For preoperative templating, the distance from the top of the lesser trochanter to the equator (LeTE) of the femoral head was measured on a calibrated digital radiograph with a neutral pelvis. This measurement was used intraoperatively to guide the choice of the trial neck and head. As with any templating technique, the goal was to construct a stable, impingement-free THA with equivalent leg lengths and hip offset. In evaluating this novel templating technique, the primary outcomes measured were the number of trial reductions and the amount of fluoroscopic time, exposures, and radiation required to obtain a balanced THA reconstruction. Using the LeTE measurement, the mean number of trial reductions was 1.21, the mean number of intraoperative fluoroscopy images taken was 2.63, the mean dose of radiation exposure from fluoroscopy was 0.02 mGy, and the mean fluoroscopy time per procedure was 0.6 seconds. In hips templated with the conventional LTC prior to the LeTE, the mean fluoroscopy time was 0.9 seconds. There was a statistically significant difference in fluoroscopy time (p < 0.001). The LeTE is a reproducible measurement that transfers reliably from digital templating to surgery. This novel preoperative templating metric reduces the fluoroscopy time and consequent radiation exposure to the surgical team and may minimize the number of trial reductions.

Abstract Background Preoperative templating in total hip arthroplasty (THA) is mandatory to achieve appropriate offset and leg length equality. However, templating methods using the contralateral hip might be susceptible to errors resulting from side-differences in the femoral morphology. The distance of the lesser trochanter to the femoral head center (LTFHD) is a frequently used reference parameter for preoperative planning and intraoperative validation during THA. However, currently no three-dimensional (3D) analysis of side differences of the LTFHD exists. Methods Using Computer tomography (CT)-based surface models from 100 paired femora (50 cadavers), side-to-side asymmetry of the LTFHD, femoral length, femoral head diameter (FHD) and femoral antetorsion were analyzed. Univariate linear regression models were established to evaluate potential associations between sides regarding LTFHD and FHD as well as a correlation of these parameters with each other. Results Statistically significant side-differences were found for the LTFHD (p = 0.02) and FHD (p = 0.03) with a mean absolute side-difference of 1.6 ± 1.4mm (range 0.1–5.5mm) and 0.4mm ± 0.6mm (range 0–3mm), respectively. The ratio between the LTFHD and FHD was consistent with an average value of 1.16 ± 0.08 and reliable between sides with a correlation coefficient (r) of 0.72 (p < 0.01). Conclusions The LTFHD is a reliable reference parameter for preoperative templating and intraoperative validation during THA with a high correlation between sides (r = 0.93, p < 0.01). However, 8 % of the investigated specimens revealed a LTFHD of more than 4mm, which should be anticipated during THA to avoid unsatisfiable results.

The Mean

This study aimed to report the outcome of total hip arthroplasty (THA) with an extensive hydroxyapatite (HA) coating for the fixation of a tapered femoral stem (Corail) in patients aged 60 or younger than sixty years with stage IV, V và VI osteonecrosis of femoral head. Subject and method: Descriptive prospective research of ninety osteonecrotic hips in ninety patients were available for clinical and radiographic analyses at minimum follow-up of 5 years. Results and Conclusion: The mean Harris hip score improved from 43.74 ± 9,25points preoperatively to 96.67 ± 3.82points at final follow-up. Seventy-four (100%) hips demonstrated stable bone ingrowth. No hips showed acetabular or femoral osteolysis radiolucency and loosening, or required revision for aseptic loosening. We believe that cementless THA with a Corail stem is a promising procedure for patients with osteonecrosis of the femoral head.

Background: There is no concrete information about many aspects of femoral fracture, including its best management. We hypothesized that reporting the outcomes of patients managed with the same therapeutic algorithm would help the selection of best management strategies. Objectives: In this study, we report the outcomes and complications of femoral head fracture in patients treated according to our therapeutic algorithm. Methods: In a retrospective review of a prospectively collected orthopedic database, 41 patients with femoral head fractures were evaluated. Fractures were classified by the Pipkin classification system. The clinical outcome was assessed with the Harris Hip Score (HHS). In brief, our therapeutic algorithm included conservative treatment for the congruous joint of Pipkin type I and II, total hip arthroplasty for unfixable fractures of Pipkin type III, and IV, and fixation via three approaches otherwise (Smith-Peterson, Kocher, or surgical dislocation). Results: Of 41 cases, 34 cases (82.9%) had uncomplicated outcomes. The number of associated injuries was significantly more in patients with complicated outcomes (P=0.049). Avascular necrosis was the most common complication (n=5, 12.2%). Their Mean±SD HHS was 85.1±109. Accordingly, HHS scoring had poor, fair, good and excellent results in 4 (9.8%), 6 (14.6%), 13 (31.7%), and 17 (41.5%) patients, respectively. The mean HHS score was significantly lower in patients with complicated outcomes (P=0.007). The mean HHS score was not associated with types of fracture (P=0.071). Conclusion: The outcome of femoral head treatment was good to excellent in the majority of patients. However, patients who underwent total hip arthroplasty or had associated injuries are at higher risk of an inferior outcome.

Background: Femoral head osteonecrosis (FHON) is a well-recognised complication in patients with human immunodeficiency virus (HIV) infection. Total hip arthroplasty (THA) is a reliable solution to FHON and has provided functional improvement and pain relief in these patients. Higher complication rates, in particular infections, have been reported in the series of THAs done in the HIV-positive patients. The purpose of this study was to evaluate the complication rate of THA for FHON in HIV-positive patients managed with the highly active antiretroviral therapy (HAART) protocols. Methods: A retrospective review was performed of HIV-positive patients with FHON who underwent THAs over a 10-year period at a single institution. Results: A total of 56 THAs (44 patients) met the inclusion criteria. The mean age at the time of THAs was 47 (range 34–60) years. Of the 44 patients, 39 (88.6%) were males. The mean follow-up was 6.6 (range 2.0–11.3) years. The overall complication rate was 12.5%, with 2 (3.6%) cases of deep periprosthetic infections. Conclusions: HIV-positive patients with FHON undergoing THAs do have a considerable complication rate (12.5%). The deep periprosthetic infection rate (3.6%) in these patients, however, has decreased with contemporary disease modification protocols.

Introduction: Osteonecrosis of the femoral head (ONFH) remains a therapeutic challenge for patients undergoing total hip arthroplasty (THA). The majority of these patients are young with high functional demand, and show an increased risk of dislocation following surgery than patients with osteoarthritis. The use of double mobility cup (DMC) has been linked with lower rates of complications when compared to conservative cups; however, the literature is scarce over DMC results in patients with ONFH. The aim of the study is to report the early outcomes of patients with ONFH treated with THA-DMC. Materials: A retrospective analysis of patients suffering from ONFH who underwent THA using DMC (THA-DMC) from 2006 to 2015 were evaluated for functional status and risk of post-operative complications. Thirty THA-DMC in 26 patients with a mean follow-up of 51 months were evaluated clinically (modified Hip Harris Score) and radiologically. Results: The mean age of the included patients was 54.9 years. At final follow-up, the mean modified Hip Harris score was 98.7 ± 2.7 and no dislocation episodes or revision surgeries were recorded. The radiological assessment revealed no signs of migration/tilting, radiolucent lines, periprosthetic osteolysis or heterotopic ossification over the DMC component and the femoral stem. The survival rate over 51 months of follow-up was 100%. Discussion: The use of the new generation of dual mobility cup in patients with ONFH showed excellent functional early results with no major complications such as dislocation.

In recent years, there has been an increase in the number of studies on the etiology of femoral head necrosis. We retrospectively reviewed all patients diagnosed with aseptic necrosis of the femoral in the period of 2010-2015. We recorded a total of 230 cases diagnosed with aseptic necrosis of the femoral head, group was composed of 65.7% men and 34.3% women, risk factors identified was 19.13% (post-traumatic), 13.91% (glucocorticoids), 26.52% (alcohol), 3.47% (another cause) and in 36 95% of the cases no risk factors were found. The results of the study based on the type of surgery performed on the basis of stages of disease progression, 8 patients (3.48%) benefited from osteotomy, 28 patients (12.17%) benefited of bipolar hemiarthroplasty prosthesis and 188 patients (81.74%) benefited of total hip arthroplasty. Osteonecrosis of the femoral head is characteristic to young patients between the age of 30-50 years old. Predisposing factors, alcohol and corticosteroid therapy remains an important cause of the disease. Total hip arthroplasty remains the best option for the patients with osteonecrosis of the femoral head.

Introduction: Outpatient total hip arthroplasty (THA) is increasingly popular. This meta-analysis investigated the potential advantages of outpatient regimes for THA. Methods: This study followed the PRISMA guidelines. PubMed, Web of Science, Google Scholar, Embase, and Scopus databases were accessed in June 2021. All clinical studies investigating outpatient THA were considered. The outcomes of interest were pain, infection, mortality, revision, dislocation, readmission rates, and deep vein thrombosis (DVT). Results: Data from 102,839 patients were included. A total of 52% (153,168 of 102,839 patients) were women. The mean age of patients was 62.6 ± 4.6 years, the mean BMI was 29.1 ± 1.8 kg/m2. Good comparability was found in age, BMI, and gender (p > 0.1). No difference was found in pain (p = 0.4), infections (p = 0.9), mortality (p = 0.9), rate of revision (p = 0.1), dislocation (p = 0.9), and readmission (p = 0.8). The outpatient group demonstrated a greater rate of DVT (OR 3.57; 95% CI 2.47 to 5.18; p < 0.0001). Conclusions: In selected patients, outpatient THA can be performed safely with optimal outcomes comparable with inpatient THA. Clear and comprehensive pre-operative planning should involve a multi-disciplinary group composed of orthopaedic surgeons, anaesthesia and rehabilitation specialists, and physiotherapists. Each centre performing outpatient THA should implement continuous homecoming welfare activity, to supervise physiotherapy and monitor anticoagulant therapy.

AbstractHospital adverse events remain a significant issue; even “minor events” may lead to increased costs. However, to the best of our knowledge, no previous investigation has compared perioperative events between the first and second hip in staged bilateral total hip arthroplasty (THA). In the current study, we perform such a comparison. A retrospective chart review was performed on a consecutive series of 172 patients (344 hips) who underwent staged bilateral THAs performed by two surgeons at a single institution (2010–2016). Based on chronological order of the staged arthroplasties, two groups were set apart: first-staged THA and second-staged THA. Baseline-demographics, length of stay (LOS), discharge disposition, hospital adverse events, and hospital transfusions were compared between groups. Statistical analyses were performed using independent t-tests, Fisher's exact test, and/or Pearson's chi-squared test. The mean time between staged surgeries was 465 days. There were no significant differences in baseline demographics between first-staged THA and second-staged THA groups (patients were their own controls). The mean LOS was significantly longer in the first-staged THA group than in the second (2.2 vs. 1.8 days; p < 0.001). Discharge (proportion) to a facility other than home was noticeably higher in the first-staged THA group, although not statistically significant (11.0 vs. 7.6%; p = 0.354). The rate of hospital adverse events in the first-staged THA group was almost twice that of the second (37.2 vs. 20.3%; p = 0.001). There were no significant differences in transfusion rates. However, these were consistently better in the second-staged THA group. When compared with the first THA, our findings suggest overall shorter LOS and fewer hospital adverse events following the second. Level of Evidence Level III.
